Is Sigma's aim smoothing busted on console?

I play on console, and I noticed that if I access Sigma’s controls while in mid game or practice mode it causes his aim smoothing to be rough and choppy, not smooth at all. I have my aim smoothing set to 0 however it feels like it’s set to 50. Has anyone else had this problem? He’s pretty much unplayable for me now, which sux cause he’s my tank main.
